Maple Buttermilk Pie with Rhubarb Compote

This Maple Buttermilk Pie comes with a hidden layer of rhubarb compote! 

Today’s easy pie recipe combines some of my favorite foods, namely rhubarb, maple syrup and buttermilk.

In one phenomenal Spring Pie.

You’ve maybe had Buttermilk Pie before. Or even – especially if you’re Canadian-  Maple Buttermilk Pie. It’s tangy, refreshing and just glorious! But the rhubarb, I tell you, the rhubarb takes this pie to a whole new level! Be prepared to fall in love!

How to make Maple Buttermilk Pie with Rhubarb Compote: 


You start by making the Pie Crust. Either use my tutorial to do so or just go with your favourite Pie Crust Recipe!

The important thing is to blind-bake the crust. You’ll find the detailed instructions on the blog post.

For the rhubarb filling, we make kind of an express rhubarb jam. As there happened to be an opened bottle of Rosé on the kitchen counter I added it to the jam!

Rhubarb and Rose Wine are very good friends. Pink likes pink! You can, of course, skip this step and substitute the wine with juice! I find it adds a little je ne sais quoi to the Pie filling!

Can I use frozen rhubarb for this pie recipe? 

I generally use frozen Rhubarb for all my Pies! When I defrost it, I always end up with a lot of lovely rhubarb juice, which I either drink pure (brrrrr…), use for sangria ( more likely) or for cooking a pretty pink rhubarb syrup!

 This time I opted for the latter and thought I might just as well incorporate it. This is totally optional but I just love the look of the rhubarb syrup drizzled on top of the whipped cream!

The Rhubarb Layer is hidden underneath a creamy, tangy Maple Buttermilk Custard! I could bathe in this custard!

The Maple Syrup adds it’s wonderfully rich and complex flavor! You will probably want to bake this again for Thanksgiving – without the rhubarb maybe!

Tips for making this Rhubarb Maple Buttermilk Pie: 

The Maple Buttermilk Pie slices pretty neatly but do make sure you give it some time to rest.

The best would be to prepare it a day in advance and to add the whipped cream and rhubarb syrup right before serving!

I find that the Maple Buttermilk Custard develops more flavour that way.

Anyways, after a few hours in the fridge, my Rhubarb Maple Buttermilk Pie came out in perfect neat slices!

If you’re a rhubarb hoarder like me, whose freezer is full of frozen sliced Rhubarb, you can have this wonderful Rhubarb Maple Buttermilk Pie all around the year.

For later in the year I can totally imagine substituting the rhubarb for strawberries!

    This is the perfect recipe to use up the rhubarb I got in my mixed vege box this week! I had no idea what to do with it as I’ve never cooked with it before. I’m feeling adventurous!

    Rhubarb all the way! It’s such a delicious and fresh summer fruit, I need to get new rhubarb plants so I don’t have frozen rhubarb, BUT I will save this recipe for later. Yum!
